[0003] However, the ceramic coating itself has high hardness and poor toughness. During use, it is easy to be bumped, impacted, scratched, etc., causing poor adhesion, cracking or falling off; and in the boiling water test, the paint film is easy to crack and fall off. It cannot meet the requirements of high wear resistance, high temperature resistance, water boiling resistance and corrosion resistance of some high-end devices (such as hairdressing equipment, etc.) at the same time

Abstract
The invention discloses high-abrasion-resistance, high-temperature-resistant and water-cooking-resistant aqueous ceramic paint, which is prepared by mixing a component A, a component B and a component C according to a mass ratio of 666: 333: 1, wherein the component A is prepared from the following components in percentages by mass: 26 percent to 30 percent of silica sol, 13 percent to 15 percent of antimony solution, 5 percent to 13 percent of inorganic high-temperature-resistant pigment and 8 percent to 12 percent of silicon dioxide; the component B is prepared from the following components in percentages by mass: 30 percent to 34 percent of silicane, 0.4 percent to 0.6 percent of wetting agent and 0.4 percent to 0.6 percent of flatting agent; the component C is 0.1 percent of catalyst. The paint prepared by the invention not only has the attractive luster and appearance and the nice hand feeling of conventional aqueous ceramic paint, but also has ultrahigh hardness and hot hardness and excellent abrasion resistance, can be up to over 100,000 times in manual hair pulling test, and further has excellent water cooking resistance, temperature resistance and corrosion resistance. The ceramic paint which is provided by the invention and is prepared by adopting a silane coupling agent has many advantages of high temperature resistance, high hardness, noninflammability, no smoke, super weatherability, environment friendliness, nontoxicity, colorfulness and the like.
Description
technical field [0001] The invention relates to the field of ceramic coatings, in particular to a water-based ceramic coating with high wear resistance, high temperature resistance and boiling resistance. Background technique [0002] Ceramic coatings belong to the field of functional coatings and are a new type of water-based inorganic coatings. It is mainly composed of nano-inorganic compounds. After coating, it is usually cured by high-temperature heating to form a coating film with properties similar to ceramics. With the development of the coatings industry, some organic coatings can no longer meet people's requirements for environmental protection, multi-functionality and excellent performance, and the development of ceramic coatings has opened up the progress and research in the field of high-tech coatings, further satisfying people's desire to improve coatings A vision of performance. [0003] However, the ceramic coating itself has high hardness and poor toughness...
